The Majin is a recurring humanoid class in the Disgaea series. One cannot become a Majin, one must be born as such. Majins possess a strong body, fearful strength, and a ruthless mind. These formidable warriors enjoy a good fight more than anything, believing that the weak have no right to live. The Dark Assembly considers them a rare resource and doesn't send them out often.

In Disgaea: Hour of Darkness, the Majin is unlocked by having a Male Warrior, Martial Artist, Ninja, Thief, and Strider all at level 200. The Majin is able to master all weapons and has some of the highest aptitudes and stat gains in the game, making them powerful units.

In Disgaea 2, the Majin becomes unlocked after completing the game, starting a new cycle, and passing the bill "Make the Ultimate Warrior". Much like their Disgaea counterparts, they have the ability to master all weapons and have high aptitudes, but their movement and throwing have been severely reduced to three and one, respectively. They have a passive ability that doubles their stats if they are the only unit left alive on the field.

In Disgaea 3, the Majin, unlocked in the same manner as in Disgaea 2, has been severely reduced in effectiveness, having no ability to master weapons and subpar aptitudes. They retain the One Man Army Evility effect from Disgaea 2 and can learn Revival, which completely restores HP if it is under 25%; Vortex, which reduces their already low Aptitudes to 10% but doubles thier base stats; and Violence, which increases stats by 50% but reduces EXP gain by 50%.
